The manager of a food court estimates that he needs 7 pretzels for every 20 people who attend a hockey game. what constant of proportionality relates the number of pretzels to people? a) 0.35 b) 2.86 c) 35 d) 140

Option: a is correct.

a) 0.35

Step-by-step explanation:

it is given that:

The manager of a food court estimates that he needs 7 pretzels for every 20 people who attend a hockey game.

it means that 20 people require 7 pretzels.

i.e. 20 people= 7 pretzel.

this means 1 person require= 7/20 pretzel=0.35 pretzel.

Hence, the constant of proportionality relates the number of pretzels to people is:

0.35.

Hence, option a is correct.  

a) 0.35

according to the triangle sum theorem, all the angles in a triangle must add up to 180 degrees. if we know one angle is already 90, we do 180-90=90. the other 2 angles must add up to 90, exactly.
